2.1 Power Requirements

The TPS26742EQ1EVM is designed to support 2 different voltage ranges that need to be configured by placing the provide shunt on J12. When the EVM is packaged, a shunt will will be installed between pins 1 and 2 to set the voltage range to the lower range of 6V to 32V.

Pins 1 and 2 6V to 32V
Pins 2 and 3 6V to 50V

The TPS26742E-Q1 EVM supports a sustained DC current of 30A. This requirement sets the input current that the external power supply needs to provide to the EVM and needs to be considered when testing the output PDO voltage and current. The table below shows the voltage that will cause the input current to the EVM to hit the 30A maximum for common dual port maximum USB Type C PD output PDO powers.

Power Delivered to Type C connector Input Voltage
100W to both port A and port B 6.67V
140W to both port A and port B 9.34V
180W to both port A and port B 12V
240W to both port A and port B 16V
